SHIELD R COVER FOR HEATERS AND STOVES FOR USE ON RAILWAY-CARS.

SPECIFICATION forming part of Letters Patent No. 383,615, dated May 29, 1888.

Application filed May 16, 1887.

To all whom it may concern:

Be'it known that I, GEORGE A. BROWN, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Safety Apparatus for Car and other Heaters; and I- do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in'the art to which it per tains to make and use the same, reference being had to the accompanying drawings,which form a part of this specification.

My invention relates to an improved safetyshield for car and other heaters, the object being to provide an apparatus to be used in connection with a car-heater that will prevent the same from setting fire to the cars in case of a wreck or collision; and with this end in view my invention consists in a shield suspended above the heater in a manner that when an accident takes place the same will drop over the heater and be secured in that position, together with certain details of construction and combination of parts, as will .be fully set forth hereinafter. I

In the accompanying drawings, Figure 1 is a side sectional elevation of my improved safety apparatus, shown in connection with a canheater, the same being constructed in accordance with my invention. Fig. 2 is a side elevation of the same. Fig. 3 is a sectional elevation of a modification of one of the temporary supports used for suspending the shield above the heater. Fig. 4 is a side elevation of oneofthespring-catches for securing the shield when the same has fallen from its elevated position.

To put my invention into practice, I provide a cylindrical shield or cover, a, open at the bottom and closed at the top, the diameter of i which is larger than that of the car-heater b, so as to leave an intervening space between the two. This shield a, I suspend above the Near the top Serial No. 236,417. (No model.)

of each of these standards c,I place africtional temporary support for the shield a, such as shown at Fig. 3 on the drawings, which consists of a bowed spring, e, placed in a recess, f, formed in the inner side of the standards 0, and backed by'a smaller spring, 9, bent in an opposite direction. These springs e g are operated by a set screw, h, bearing against the smaller spring, 9, by which means the required degree of pressure may be brought to bear against the sides of the shield a, in order to support the same above the heater 7). At the base of the shield a, I secure several hooks, t, which engage with a similar number of spring catches, j, secured to the floor of the car when the shield a has dropped. At the top of the shield at, I secure-a pipe, 70, which encircles the draft-flue Z of the heater 1). This pipe 70, I construct in sections, telescoping the one with the other, in order that the same may not project above the roof of the car when the shield a is suspended above the heater b. On the inner surface of the shield at, I arrange a suitable number of braces, m, which will retain the heater b in its proper position in the shield a, should the car be overturned. To the ceiling of the car I secure several pulleys, a, over which are suspended two weights, 0, by means of cords 10, attached by hooks q to the shield a. This arrangement is used to lift the shield a above the heater b, and is disengaged from the same after the friction-springs have been properly adjusted.

In operation the shield a is suspended above the heater b, as shown at Fig. 1 on the drawings. The friction-springs are given the required degree of pressure against the sides of the shield. Should a collision of the cars holding the said shield suspended, theverti the braces m, theholding-down devices ij, and cal standards 0, the braces m, fixed to the inthe pulleys and loaded cords for elevating the 10 terior of the shield, the books i, and springshield, all substantially as specified. catches for holding the shield over the heater 5 after the shield falls, substantially as specified.
